Verdict
The clearest difference is ads: 99 Problems at none against Stack Jump's shown. 99 Problems also leads on review sentiment (74% vs 48%) and iOS requirement (6.1 vs 13.0). Stack Jump's advantage is ratings volume (299K vs 38) and rating (4.6 vs 4.3). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. 99 Problems sells 1 one-off in-app purchase and Stack Jump sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Stack Jump holds the better App Store score, 4.6 against 4.3. That said, the two scores are not equally well evidenced: Stack Jump has 299K ratings behind it against 38, so its average is the more settled of the two. Written reviews complicate that: 74% of 99 Problems's written reviews are positive against 48% of Stack Jump's, so the app with the better star average is not the one people write more warmly about.
99 Problems ships an update every 3 months, Stack Jump every 4 weeks. The most recent releases landed on September 7, 2026 and September 27, 2026 respectively.
